African lily 'Phantom'

Grow in containers in loam-based compost such as John Innes No. 3, water freely when in growth but sparingly in winter, and apply a balanced liquid fertilizer monthly from spring until flowering; in mild areas, grow outside in moisture-retentive but well-drained soil in full sun, and provide winter protection with a dry mulch; for more advice, see Agapanthus cultivation

No pruning required except cutting back dead flower stems, but allow them to remain until spring, because the seedheads look attractive over winter

Propagate by division between spring and early summer, or in early autumn after plants have finished flowering

Generally pest-free but may be affected by slugs and snails and by agapanthus gall midge

Generally disease-free but may be affected by virus diseases
